Objectives: The purpose of this study is to identify the importance of perception and communication ability among dental hygienists and provide evidence for the activation of communication education necessary to improve communication ability required in the actual dental field. Methods: A questionnaire survey was conducted on 227 members attending conservative education in 2020. Results: The following are mean scores of each area of communication according to importance: message conversion ability, 3.82 points; interpretation ability, 3.74 points; goal setting ability, 3.51 points; self-expression ability, 3.48 points; and role performance ability, 3.46 points. The ability was interpreted in the following order: interpretation ability, 3.61 points; message conversion ability, 3.56 points; role performance ability, 3.43 points; self-expression ability, 3.32 points; and goal setting ability, 3.10 points. The highest score in terms of importance of awareness was 4.27 points, the highest among interpretive abilities, that is, to 'listen carefully to know what the other person intends to say.' When it comes to communication skills, the highest score was 4.12 points for 'a nod or a facial expression of understanding while listening to each other.' Conclusions: In devel oping a training program related to communication for dental hygienists at the clinical site, the curriculum reflecting seven items that needs improvement should be revised; and through this, it is expected that dental hygienists' communication skills will be improved.

This study is the result of meta evaluation for the self evaluation of defense R&D programs in Korea. The overall meta evaluation result of defense R&D programs gained 74.3 points out of 100, so it was evaluated as 'Good'. But it demonstrated that further improvement for overall system of defense R&D programs evaluation is required. And especially, it demonstrated that more alternatives are necessary in order to improve the utilizations and the feedbacks of evaluation results. The evaluation context component gained 80.2 points out of 100, so it was evaluated as 'Very Good'. The evaluation input component gained 73.1 points out of 100, so it was evaluated as 'Good'. The evaluation process component gained 74.8 points out of 100, so it was evaluated as 'Good'. From the analysis, it is attempted to identify possible problems and to find out the ways of improvements related to the self evaluation system of defense R&D Programs.

The cycloconverter operating on a circulating current-free mode has many zero crossing points. If an exact zero crossing points are not detected, the three phase-unbalanced currents will flow in a motor. In this paper, the current feedback using a current reference wave is proposed to improve the problems of zero crossing detection, three phase-unbalanced voltages, currents, and torgue ripples. To prevent the saturation of the air gap flux and keep the torque constant, the constant voltage / hertz control with IR compensation is adopted. The PI-controller is designed using the linearized model of the cycloconverterinduction motor system. Alsi, Z-80A single board computer has been used to implement the proposed scheme which results in the performance improvement of cycloconterter-fed induction motor speed control system.

This paper proposes a new multi-start scheme that generates guided random bits in selecting initial search points for global optimization with univariate dynamic encoding algorithm for searches (uDEAS). The proposed method counts the number of 1 in each bit position from all the previously generated initial search matrices and, based on this information, generates 0 in proportion with the probability of selecting 1. This rule is simple and effective for improving diversity of initial search points. The performance improvement of the proposed multi-start is validated through implementation in uDEAS and function optimization experiments.

This survey intends to understand the opinion and status on preschool students' uniform wearing for the purpose of new style development. The results from this study will serve as an activator of related industry. The merit of uniform wearing in these students was recognized primarily as: (1) students can have pride in the schools they attend; (2) they need not worry about clothes to wear every morning. The disadvantage of uniform wearing derives from: (1) students' personality is hardly expressed by uniforms; (2) difficulty in uniform selection suitable for varying weather conditions. This disadvantage felt by their parents suggests the lack of personality expression and appropriate body temperature control. The most prevalent opinion for preference and future improvement points was the consideration of physical activity in children. This indicates that they prefer uniforms rendering minimal restriction on body movements. Other Improvement points stress the activity, uniform laundering and care, convenience in on and off, insulation, colors, design and durability.

A variable bit rate speech coder is presented. The coder is based on the observation that a speech signal can be viewed as a combination of piecewise linear signals in a short time period. The encoder detects the sample points where the slope of the signal changes, which are called the inflection points in this paper. The coder transmits the location and value for the detected inflection sample, but only the location information for the noninflection samples. In the decoder, the noninflection samples are estimated with interpolation of the received information. Several factors affecting the performance of the coder have been tested through simulation. Simulation results show that the linear interpolation produces 1 ~ 5 dB improvement over the cubic spline interpolation. And the -law companding does not provide any benefit when it is applied before the inflection detection. With low threshold values in the inflection point detection, the coder shows better MOS and more than 16 dB improvement in SNR compared to the continuously variable slope delta modulation (CVSDM).
